Abstract

Disclosed is a composition comprising a layer carrying an organic oxygen scavenging material and a polymeric selective barrier layer. The polymeric selective barrier layer permits oxygen to migrate from the packaged volume to the organic oxygen scavenging material, and the polymeric selective barrier layer blocks migration of compounds created during oxidation of the organic oxygen scavenging material from the layer carrying the organic oxygen scavenging material to the interior of the package in which the composition of this invention is incorporated. In one embodiment, the polymeric selective barrier layer has a glass transition temperature greater than about 5 degree C above the use temperature of the package in which the composition of this invention is incorporated. In another embodiment, the polymeric selective barrier layer has a glass transition temperature greater than about 40 degree C. In yet another embodiment, the polymeric selective barrier layer is an oriented polymer. In a further embodiment, the layer carrying the organic oxygen scavenging material is a polymer having oxidizable sites in the polymer and containing a transition metal salt catalyst.
